"Stuart Hogg has got quite a nasty bruise under his eye and a gash under the ear," he said.

"He’s just caught Conor Murray’s elbow. He was a bit unlucky in that situation. He was looking dangerous in attack.

"Both he and Jonathan Davies failed the HIAs. The return to play is a minimum of six days and they will just go through the protocols. We will play it by ear over the next few days."

It's currently unclear as to whether or not Wales fly-half Dan Biggar will be available to face the Highlanders on Tuesday.

He also failed a HIA, in the defeat to the Blues, and his minimum six-day rest is up on Tuesday. However, if he is still showing concussive symptoms, then Johnny Sexton could be asked to play his fourth straight game of the tour.
